คำอธิบายเพิ่มเติมในรายละเอียด
----------------------------------
Data in a CD-ROM is organized in frames and sectors.
The smallest entity in the CD format is called a frame, and holds 24 bytes.
A CD-ROM sector contains 98 frames, and holds 2352 bytes.

These codes help prevent the data from becoming corrupted
, which could lead to errors for executable data.

ดังนั้น สิ่งที่ตามมาก็คือ
an "ISO" is created by copying an entire disc, from sector 0 to the end, into a file.
Because the image file contains "cooked" 2048-byte sectors and nothing else
, it isn't possible to store anything but a single data track in this fashion.

The Mode 1 CD-ROM ECC is independent of
and in addition to the CIRC encoding.
It uses a Reed-Solomon Product Code (RSPC)
to achieve a combined error rate of 1 error per 1e15 (quadrillion) bits.

MODE-2
----------
Mode 2 provides 14% more user data space than Mode 1
by omitting error correction
, since a read error in audio or video
will only cause a small flaw
which may not even be detectable to humans.
